An Extremely Accurate and Precise Valve Positioner

The EL electropneumatic positioner combines the precision and adaptability of a digital electronic control circuit with the smoothness and efficiency of Kinetrol's proven proportional servo valve, to give the best available 4-20mA positioning performance from rotary pneumatic actuators. 

This unbeatable performance is combined with the easiest available setup procedure, easiest access to all functions and options, easy connectibility, and a truly compact all-metal enclosure, plus unique easy-set isolated angle retransmit and limit switch options inside the same enclosure.

Features

• Fast, smooth and precise control from a digital circuit and proportional servo valve 
• Simple time saving field set up
• Quick calibration via push buttons and LED feedback and easy reversal of rotation sense (clockwise/counter clockwise) without special tools or parts change. 
• Universal application
• The unit can be mounted in any orientation on to any quarter turn or linear application by connection via a NAMUR or Kinetrol square interface. 
• Loop powered
• No separate power needed, just a 4-20mA signal plus air supply. 
• Integral options - easily retrofitted modules include:
• Two wire 4-20mA isolated angle retransmit 
• Mechanical or inductive position indicator switches (general or hazardous areas) 
• Clear Cone high visibility indicator 
• Threaded conduit entries or DIN plugs for external connection.
• Intrinsically safe approved options 
• Weatherproof, compact and robust metal housing 
• Zero backlash coupling with easily adjustable switch strikers 
• Vibration and shock resistant to 4G 
• Built in gauge ports/external connections

Work with a Valve Automation Professional on Your Next Project for Improved Outcome and Efficiency

The valve automation
sales professional
will help with your next project.

Projects requiring engineered valve systems are best completed and accomplished through the proper selection and application of the valves, actuators, positioners, limit switches and other associated components. A great resource exists, ready to provide a high level of technical knowledge and assistance, that can be easily tapped to help you with your project - the valve automation sales professional.

Local distributors and representatives who sell industrial valves, actuators and controls also provide services and equipment that will save you time, money, and help you achieve a better outcome for the entire project.

Consider a few elements the valve automation professional brings to your project:

Product Knowledge: Valve automation professionals are current on product offerings, proper application technique, and product capabilities. They also posses  information on future product obsolescence and upcoming new designs. This type of information is not generally accessible to the public via the Internet.

Experience: As a project engineer, you may be treading on new ground regarding some aspects of your current valve system design assignment. There can be real benefit in connecting to an experienced and highly knowledgable source, with past exposure to your current challenges.

Access: Through a valve automation professional, you may be able to establish a connection to “behind the scenes” manufacturer contacts with essential information not publicly available. The rep knows people at the factories, a well as at other valve related companies, who can provide quick and accurate answers to your valve automation related questions.

Of course, any valve actuation or automation solution proposed are likely to be based upon the products sold by the representative. That is where considering and evaluating the benefits of any solution becomes part of achieving the best project outcome.

Develop a professional, mutually beneficial relationship with a local valve automation professional to make your design job go after, more efficiently, and more cost effective. Their success is tied to your success, and they are eager to help you.

Use Vane Actuators on the Toughest Applications

Use vane actuators on
tough applications.

The "vane type" pneumatic valve actuator is well regarded for its simplicity in design and extremely long life, even in the toughest valve actuation applications.

The heart of this simple design, and the primary reason for such long life, is the "single moving part" - a one-piece shaft and vane that moves in response to the air pressure differential on either side of the vane. A rotary vane actuator has no gears or yokes which will wear and cause problems over time. Wear, movement slop, and internal corrosion are the most typical modes of failure for rack and pinion and scotch yoke actuators.

The video below illustrate the elegance and simplicity of the rotary vane actuator and its "single moving part".

Louver and Damper Control with Vane Actuators

Besides pneumatic valve actuation, Kinetrol vane actuators are used widely on controlling industrial and commercial louvers and dampers.

The video below gives you a short visual demo of a louver being opened, closed and positioned with a Kinetrol vane actuator and electro-pneumatic positioner.

Louvers and dampers are used to stop or regulate the flow of air inside a duct, chimney, air handler, or other air handling equipment.

Some varieties of dampers are:

• Louvered Inlet Box Dampers
• Radial Inlet Dampers
• Variable Inlet Vane (VIV) Dampers
• Vortex Dampers
• Discharge Dampers

Industries that use dampers include:

• Petrochemical
• Oil & gas
• Power generation
• Construction industries
